Facebook Chat Encrypter

Interestingly/unfortunately Facebook (after the publicity from: TechCrunch,
BGR, lifehacker)
have 'clocked on' to Crypter and to our regret, no longer encrypts. We will be working extremely hard on
another way around, so still download the extension as an update will be pushed out automatically. We at
Crypter are really sorry about this. If you want to try give us a hand visit GitHub.

This Chrome/Firefox extension locally encrypts and decrypts your Facebook messages using AES encryption along with a preset password.

ABOUT

Crypter works by first agreeing upon a password between the sender and receiver (we recommend using our
online self destructing messaging service ⊗.cf). This password is
then used to locally encrypt messages on the sender side, creates ciphered text, which is sent across
the Facebook server, and is then used again to locally decrypt the ciphered text on the receivers’ side.
It is powered by the Crypto-JS library using AES (Advanced Encryption Standard) encryption methods.

We had an “if you can’t beat them, join them” attitude, to designing Crypter. Instead of inviting users
to join a brand new chat application we decided to apply it to an already established one – Facebook.
And at the same time making sure that we don’t interrupt with our users existing habits.

Unencrypted conversations leave people’s private conversations vulnerable to interception from private
companies and Governments without user consent. This is a growing concern with laws such as the
‘Snooper’s Charter’ being introduced in the UK and SOPA and PIPA in the US. These would allow our
Governments’ to intercept our private messages without the need of a warrant from law enforcement or
consent from the users.

Because of the issue Crypter solves, it leaves itself open to be useful in a multitude of ways. In
countries where Governments can persecute and kill for inciting protest, having a tool like Crypter
would be incredibly beneficial for the oppressed. They can now use social media to spread and share
ideas. Having something akin to Crypter could have completely rewritten history in respect to events
like the Arab Spring.

In times where it’s of concern that social media companies sell your data to advertising companies in
order to provide targeted advertising, using Crypter could be immensely valuable. Your messages become
totally illegible to prying eyes rendering them useless to advertising companies.

It’s human nature to want privacy. In light of Edward Snowden’s Global Surveillance disclosures, people
don’t want their messages stored and analysed regardless of whether their topic of discussion is
illegal. Crypter can put millions of people at ease.

Crypter solves the issue of getting unwanted hands on your Facebook messenger data, and we believe this
to be incredibly important in 2016 where Internet privacy is at the forefront of debate. It’s a current,
global issue affecting 1.55 billion people worldwide. Having an unobtrusive application like Crypter
emerge into the market now would immensely aid efforts to increase Internet autonomy.

HOW TO SET THE PASSWORD

To set the session password, click on the lock icon when the text field is empty. You and the person
you’re chatting to must have the same password to ensure you can encrypt and decrypt messages correctly.

HOW TO ENCRYPT

To encrypt your message, type in your desired message as normal and then press the lock button. This
will then convert your message into ciphered text and you can send it as normal.

HOW TO DECRYPT

To decrypt a message you’ve received, press the lock that appears in the chat box. To turn it back into
the encrypted lock, double click the message.

You can also have the app both auto encrypt and decrypt messages by clicking the check box where you set
the password.
